Sulzer Submersible propeller Pump Type ABS VUPX


Sulzer's submersible propeller pumps are designed for applications requiring the pumping of large volumes of water at low heads up to 10 meters. These pumps are equipped with highly efficient Premium Efficiency IE3 motors, ranging from 9 to 650 kW for 50Hz and 19 to 1005 hp for 60Hz. Optional planetary gearboxes are available for models with motor power up to 650kW / 50 Hz and 1005 hp / 60 Hz.

The pumps feature highly efficient three- or four-blade propellers with excellent NPSH values and are ideal for direct installation in discharge pipes or concrete risers to save space and reduce installation costs. Adjustable blades and special skew-shaped propellers are available for return-activated sludge applications. The well-proven coupling ring design ensures improved energy savings and long-term reliability.
